INTRODUCTION

The QC Electromagnetic Overhead Crane is a double-girder bridge crane equipped with a detachable electromagnetic spreader (magnetic chuck/beam). Driven by an electric current to generate a powerful magnetic field, it seamlessly attracts, lifts, and releases magnetic metal materials.

APPLICATION SCENARIO

1. Steel & Metallurgy Industry
The primary application for QC cranes. Used for handling and stacking steel ingots, steel plates, structural steel (H-beams, I-beams), continuous casting billets, and hot-rolled/cold-rolled coils. Also used for the recycling and transportation of pig iron blocks, scrap steel, and iron shavings. Designed to withstand high-temperature environments and suitable for frequent loading and unloading operations.-

2. Mechanical Manufacturing & Processing
Used for handling large castings and forgings (such as machine tool bases and engine housings), positioning and installing steel beams and steel plates in metal structure workshops, and recycling scrap materials such as machining chips and stamping scrap. Suitable for both indoor workshops and outdoor yards.

3. Port Terminals & Logistics Warehousing
Used for loading and unloading steel and metal coils onto ships, transferring scrap metal within container terminals, and sorting and storing steel in large warehouses. Outdoor models come equipped with rainproof and corrosion-resistant designs.

ADVANTAGES

1. Non-Contact Handling
The electromagnetic chuck absorbs metal materials without physical clamping devices, making it ideal for handling steel plates, billets, and other magnetic materials. There is no need for packaging, binding, or boxing, simplifying the entire handling process.

2. High Efficiency & Energy Savings
The crane can adjust electromagnetic force as needed, minimizing unnecessary energy consumption. It can quickly absorb and release goods, significantly shortening the operation cycle and improving overall work efficiency.

3. Safe & Reliable
A backup power supply or mechanical locking device is usually provided to ensure that goods will not suddenly fall in the event of power failure. The dual-mode unloading system (active demagnetization via reverse current pulses and passive demagnetization via gradual power-off) prevents impact loads and ensures complete workpiece separation.
